Carefully wash the tomatoes, removing any bits that look a bit duff.
Peel, core and chop the apple.
Chop the tomatoes and onion (and the very small green pepper)
Mix the tomatoes, apple and onion in a large pan. Add the sugar and vinegar and stir with a wooden spoon.
Add the chilli and ginger, and stir again.
Bring to the boil, then turn right down to minimum heat and leave to simmer for at least an hour, stirring every 15 minutes or so, until it becomes a lot less runny and a lot more sticky and jam-like.
Pour into sterilized jars and allow to cool.

The whole house now smells of really fantastic vinegary chutney smells that remind me of Christmas!
